Accurate Fault Location Using Deep Belief Network for Optical Fronthaul Networks in 5G and Beyond

IEEE Access, 2019
In face of staggering traffic growth driven by fifth generation (5G) and beyond, optical fronthaul networks which host such connections require efficient and reliable operational environments. Fault location has become one of the primary factors for post-

Microservice Adaptability and Self‐Organization of UAV‐Assisted Wireless Networks in Failure Rural Scenarios

International Journal of Distributed Sensor Networks, Volume 2025, Issue 1, 2025.
Internet access remains unavailable for approximately 2 billion people in remote areas, limiting their access to essential services such as healthcare and education. This paper presents a UAV‐based wireless network architecture combined with a microservice model to ensure the dynamic deployment of IoT applications in rural environments.

Testbed Verification of New Fronthaul Technology for 5G Systems [PDF]

2019 IEEE International Conference on Communications Workshops (ICC Workshops), 2019
The fronthaul for 5th generation mobile systems (and beyond) has evolved with new splits for the radio access network functions defined, and the transport for these split interfaces having very different requirements. Testing of the transport for such split interfaces is reported, and it is shown that an Ethernet fronthaul transport network, which is ...

Design and Optimization of a Phase‐Tunable Mixer Based on Cascaded Dual‐Drive Mach–Zehnder Modulator Considering Nonlinear Behavior of Modulator

International Journal of Optics, Volume 2025, Issue 1, 2025.
This paper proposes a novel phase‐tunable mixer based on a cascaded dual‐drive Mach–Zehnder modulator (DDMZM), designed to address the critical need for simultaneous frequency mixing and precise phase control in phased array antennas. Unlike conventional mixers, the proposed structure uniquely combines frequency mixing and phase tuning, enabling ...

All-Optical Network Capacity for 5G Cellular Fronthaul

2019 21st International Conference on Transparent Optical Networks (ICTON), 2019
In this paper, we have investigated the use of fast wavelength switching optical transmitters and a wavelength selective space switching all-optical network for cellular fronthaul applications. System capacity is calculated by using hard-deadlines that arise from the radio requirements and the physical constraints of the optical network.

Delay aware resource allocation in ORAN through network optimization

IET Wireless Sensor Systems, Volume 14, Issue 6, Page 528-538, December 2024.
This Figure shows the basic design of open radio access network architecture, in which the virtual machines collaborate within the physical servers. Abstract A multi variable resource allocation problem is investigated in network environments, specifically focusing on the consideration of quality of service in open radio access network.
